Ask Engadget: best 'Find my Phone' app for Android?

We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget inquiry is coming to us from Jacob, who needs to ensure he can find his Android phone if it's lost. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com.

"Hi good folks at Engadget! I just upgraded to a Galaxy S III and I need a new "find my phone" tool. I used to use SeekDroid on my DROID 2, but the web interface won't work on the new phone. I know Samsung's got an app called DIVE that can do this, but it doesn't seem to be supported on Verizon phones. If you've got any suggestions, that'd be fantastic. Thanks!"

Actually, we had a look and we don't think it's available on any US Samsung handset without flashing your firmware. But let's imagine he doesn't want that level of hassle. What app should he be picking up? Where's my Droid? Plan B? Something else? What's worked for you -- share your wisdom.
